COIVIIBINED GAS AND: COAL RANGE.

`Specification of Letters Patent. Patented June 24, 1919.

Application filed une 8; `1916. Serial No. 102.424.

To all whom t may concern:

Be it known that I, OTTO Sinonimi, a citizen .of the United States of America, residingat the city of Belleville, county of St. Clair,`

State of Illinois, havenvented a certain new and useful' Combined Gas `and Coal Range, of which the following is such a full, clear, and exact description as will `enable any one skilled in the art to which it appeitainsto inake and usethe saine,reference being had` to the accompanyingdrawings,"

forming part of this speciiication.

My invention relates to a' combined gas and coal range and more particularly to one` in which the gas heating attachment may be readily removed and placed in position. In the accompanying drawings which illustrate so inuch ot a range as is neces` sary to disclose my invention, Figure 1 is a j vertical section through the oven; Fig. 2 is a section taken on the line 2-.2 oi Fig. 1; Fig. 3 is an enlarged detailed view of the valve for controlling the outlet of air;` Fig.`

4 is a view similar to Fig. 3, but showing the valve in a diii'erent position; Fig. 5 is 'a horizontal section through the oven.; Fig. 6

is an enlarged sectional view. of the burner;`

9; back 10; ends 11-12; top 13 and door 14. Passing below the bottoni 9 `is a flue 15, connected from the lire pot (not shown) which is arranged as is usual adj acent to the end 11 of the oven.. This `flue 15 communi- Cates with an upwardly` extending flue 16 adjacent to the end'12, andthe Hue 16 in turn communicates with a flue 17, passing over the top 13 of the oven into the chimney flue 18. All of these` parts maybe of any usual and well-known construction.`

Arranged withinthe oven is a `baille-plate 20 supported on feet 21. This baiieplate 20 is made thicker at the end adjacenti` to thewall 12 than at that adjacent tothe wallll, as is best shown iii Fig. 1 of the' C lrawings.` The baille-plate is preferably formed oi a base 22, of cast metal; a covering 23 ,of

. sheet `metal and a illing` 24 of asbestos or other noii-conducting material. In order to insure the proper positioning of the `baiiieplate inthe oven, I provide it with a pair of lugs 25 adapted to bear against the back 10, and with a pair of lugs 26 adapted to bear against the wall 11, and a pair of lugs 27 adapted to bear against the wall 12. As will be seen in Fig. 5 of the drawings the lugs 26 are considerably longer than the lugs 27, so as to leave an air passage of greater area between the ends of the `battleplate and thewall 11 than that of the passage between the end of said plate and the wall 12, in order to secure thelproper circulationot the heated air, as will be herein* after more fully set forth. It `will be understood that the baffle-plate can be readilyv removed and placed in any position in the Secured to the bottom of thebaiiie plate is a burner 29, shown in detail iii Fig. 6. The burner is supplied with gas by an L- shaped pipe 30, the endof which is provided with a mixer Bland is adapted to project through an opening 32 in the back 10 of the oven. Themixer 31 makes a sliding connection with a gas supply pipe 33 carriedin a bracket 34. The burner 29 is provided with thickened portions or ribs at each side, as is shown in Fig. 7, and in these ribs are formed the burner holes 36. The opening 32 not only allows the passage ot the mixer 31, but also supplies air to the` oven when the same` is used in connection with the gas burner. It is necessary, however to close this opening when the range is used as a coal range.` In order to close this opening I provide a door 37 sliding in guideways 38. This door 37 is attached to the end of a chain 39, which passes into a shallow trough 40 and is attached to the end of a slide 41, the movement of said slide being controlled by a knob 42 projecting through aslot 48 in the bottom of the tro-ii,gih.` The slide 41h-as secured `to itl an arm 44 projecting through a slot 45 in the side of the trough 40.` The arm 44 is bent down, as is best shown in Fig. 1 ofthe drawings, and

is adapted to make contact with two` lugs 46 and 47 respectively on a valve plate 48 controlling openings 49 formed in the uppeiwpart `of the wall 12 and adaptedto control `the fflow of heated air from the oven into the flue 16. The distance between the lugs 46 and `47 is such that the valve 48 will only be moved a short distance, as shown in Figs. 3 and 4 of the drawings, while the door 37 will be moved a much greater distance. In order to allow the air to enter at the front of the oven the oven door 14 is provided kwith openings 50, controlled by a slide`51, provided with a corresponding number of openings 52 and having a lug 53 projecting through a slot 54, so as to be operated from the outside of the oven. 55 is a match-scratcher which is secured on the balie-plate 20.

The operation of my range is as follows: Then it is desired to use the range as a gas range the baille-plate and attached burner are inserted into position, as best shown in Fig. 5 of the drawings. When the burner 29 is lighted the heated air passes upwardly around the four sides of the baille-plate. Inasmuch, however, as the space adjacent to the wall 12 is less than that to the wall l1, a considerably greater amount of heated air is caused to pass up adjacent to thewall 11, and this, together with the wedge-shaped section of the baille-plate secures an even distribution of the heat throughout the oven, as the heat all passes out through the openings 49 into the flue 16.

When it is desired to use the range as a coal range, itis only necessary to withdraw the baille-plate 20, which can be readily done, as it is not permanently connected at any point, the join-t between the mixer 31 and the supply pipe 33 being a slip joint. After the baille-plate and burner have been removed from the oven the knob 42 is moved rearwardly so as to allow the door 3l' to move downwardly inthe guides 38, thus closing the opening 32. As the slide 41 reaches the-end of its movement the arm 44 will come into contact with the lug 46 and valve 48, thus moving the said valve into the positioin shown in Fig. 4,'clo'sing the opening 49,"so that the oven does not communicate `with the iue V16, and consequently the gases from the burning `coal will be prevented from entering the oven.

It will be seen that my range is simple and effective in operati-on, and readily changed from a gas range to a eoalfrange.

Having fully described my invention, what I claim as new and desire to secure by LettersPatentof the United `States is:
